Jeffrey just returned from the Munich Security Conference. On his way back, he passed through DC where he sat down with Aaron and Scott to discuss NATO, extended deterrence, intermediate-range nuclear forces like the RS-26 and the SSC-8, and what makes for an ideal beer hall.

Donald Trump ordered up a new Nuclear Posture Review and reportedly told Vladimir Putin that the New START arms control treaty was a bad deal -- after first asking his advisers what it was. We don't know whether Trump really hired two Russian hookers to pee on Obama's hotel bed in Moscow, but Jeffrey tells Scott that the President is certainly directing a warm stream of abuse toward Obama's nuclear legacy.

Jeffrey and Scott celebrate the Lunar New Year by sharing two stories about how the moon featured in the arms race.

Scott talks about plans to nuke the moon in project A119, while Jeffrey discusses how a young Bill Perry helped the US monitor Soviet radars by intercepting the signals reflecting off the lunar surface.

Trident’s latest test was rather underwhelming. The missile's flight trajectory was error filled and flew at an unintended target (Disneyworld). Why? The dastardly grey weather, or something more pernicious. Is our dear Dreadnought in trouble? Tune in and find out.

Jeffrey and Aaron have a gentlemanly discussion about the British strategic deterrent. Tea will be served.

If you study nuclear weapons, you study something secret. Not surprisingly, we spend a lot of time in the arms control community thinking about intelligence estimates. Jeffrey and Scott take a break from the bomb to talk analytic method. The Trump documents dumped on Buzzfeed are as good an excuse as any to discuss the role of analysis in making sense of raw intel.

In the mid-60s, The Green Hornet was a popular TV show. Popular enough for the Taiwanese to apparently name an early ballistic missile after it, the Green Bee (青蜂). Also, did you know Taiwan had its own ballistic missile program? Its anti-ship and cruise missiles tend to make the news, but Taiwan has a storied and strange history with ballistic missile proliferation that involves the infiltration of American universities, the laundering of missiles, and Israel.

Jeffrey and Scott sit down to discuss Taiwan's history with ballistic missiles with data fresh from Jeffrey's primary source research.

Can the North Koreans still trade coal effectively? What is going on with North Korean ships? Are transit lounges smokey dens of proliferative behavior?

Andrea Berger, Deputy Director of Proliferation and Nuclear Policy at the Royal United Services Institute, joins Jeffrey to talk about UNSC 2321 and recent UN attempts to close the loopholes in existing sanctions on North Korea.
